Add in-view incremental Find (Ctrl+F) with match highlighting

[jschick04]

Summary

Adds an in-view incremental Find (Ctrl+F) to the log-table pane (ADO 62704674). It is a component-local overlay over the current filtered view: it never dispatches a filter / lens / sort / selection action, it only reads the view to derive matches, scrolls the current match into view, and (in grouped mode) toggles group collapse to reveal a hidden match.

What's included

• Ctrl+F opens a floating find bar; Esc closes it, restoring grid focus and landing the cursor on the current match.
• Incremental, debounced search as you type, over the enabled columns plus the Description of the current view.
• Match count shown inline as N/M; prev/next navigation (buttons, Enter / Shift+Enter, F3 / Shift+F3) with wrap-around and a screen-reader wrap announcement.
• Match case and Match whole word toggles in an options tray. Whole-word uses VS Code's wordSeparators boundary rule (correct for EventIDs, GUIDs, and hyphenated provider names, and still findable for punctuation-edged queries like .NET / -Auditing).
• Highlighter-yellow inline marks on the current match's cells; a neutral inset ring on every match row (weight-encoded 1px vs 2px for other vs current), with a forced-colors / high-contrast outline fallback.
• Group-aware navigation: expands a collapsed group to reveal a match and re-collapses groups Find opened once you navigate away, while relinquishing ownership when the user bulk- or context-toggles groups.

Implementation notes

• Pure matcher (EventFindMatcher) in the Runtime layer: RowMatches / IndexOfMatch / whole-word IsWordBounded, Ordinal comparison for machine-shaped cell text, shared by the row scan and the current-match mark splitter so highlighted spans are exactly the spans that counted as a match.
• The match set is computed on a background, cancellable, epoch-and-identity-gated scan and published on the renderer thread.
• Mark rendering is XSS-safe: Blazor-escaped segments (never MarkupString), capped per cell against a pathological hit count.
• Global Ctrl+F is routed via a singleton FindCoordinator bridge (keyboard shortcut -> currently-mounted pane), mount-order-safe across WebView reloads.

Validation

• Test suites green: Runtime 1800/1800, UI 1103/1103. Touched projects build 0 warnings / 0 errors.
• New tests: EventFindMatcherTests (18, incl. a whole-word Theory), FindBarTests, LogTablePaneFindTests.
• Governance: pre-implementation + post-code multi-model panels 5/5 during development; pre-push review panel over the committed diff.

Manual acceptance (WebView2)

Visual / interaction outcomes automated tests can't verify:

• Ctrl+F open / Esc close; incremental highlighting; prev/next with wrap; count centering.
• Match case + Match whole word toggles; yellow marks + neutral rings in light and dark; forced-colors / high-contrast.
• Grouped view: navigating into a collapsed group and back out.

Pull request overview

Adds an in-pane “Find in view” experience for the log table (Ctrl+F) that scans the currently displayed rows (without altering filters/sort/selection), supports incremental navigation, and renders accessible match highlighting (including group-aware behavior).

Changes:

• Introduces a Find overlay (FindBar) with incremental search, navigation, and options (case/whole-word), plus UI highlighting styles.
• Adds LogTablePane-side find state management and background scanning using a shared runtime matcher (EventFindMatcher).
• Routes Ctrl+F through the keyboard shortcut bridge via a singleton FindCoordinator, and adds unit/UI tests.
